Preheat the oven to 350 degrees F. Line a muffin tray with 9 muffin papers.
Add all ingredients except the grated zucchini to a blender. Blend until completely smooth. Stir in the grated zucchini until well-combined.
Fill the muffin holes up ⅔ to ¾ of the way full. Bake on the center rack of the preheated oven 30 to 35 minutes, or until muffins are golden-brown and cooked through.
Allow muffins to cool at least 30 minutes before eating. I suggest enjoying these muffins with a pat of butter and a drizzle of honey.
